Letters Patent No. 104,805, dated .Teme 28,1870.

The Schedule referred to invthese Letters Patent and making part of the lame I, IsAAc I. WENDELL, of the city of Philadelphia, and State of Pennsylvania, have invented certain improvements in Lubricating J onrnal Bearings, of which the following is a specication.

The Anature of my invention consists of an oil-box for lubricating the journal, which has a closed top, hav- -ing a concave face for catching the oil which escapes from the journal, and which is constructed with a vertical space, for containing felt, and side oil-chambers, which have communication with said space by means of openings in vertical partitions which separate the space from the chambers, iu such a manner that the oil contained in the chambers keeps the felt in said space wll saturated with oil, which is 'cmistantly supplied to the jourual'by capillary attraction, the upper edgesv of the felt protruding through a-siot in the top of the box`.

The oil 'being inclosed, and perfectly frec from dust, removes the ditlicultyl experienced in feeding through porous material in an open box.

To enable others skilled in` the art to which my improvement appertains to make.and use my invention, I will now give a detailed description thereof.

In the accompanying drawing, which makes a part of this specificationlFigure 1 is an ordinary car-box, with the improved lubricating device in connection.

Figure 2 is a cross-section of the saine.

Like letters in both iigures indicate the same parts.

A is an ordinary car-box.

'B is the journal of the shaft in connection therewith; and l O, a brass bearing, all constructed in the ordinary manner. y

The lubricating device which constitutes the invention is constructed as follows D is an oil-box, whose upper concave surface, a, nearly touches the journal.' v

The box is held up in position by means of the spring E, which rests upon the upper surface of the bottom of the box A, and it is held in its lateral position by means of the annular rim b, on the under side of' the oil-box D, as seen in the drawing.

The said oil-box D has vertical partitions c c, between which I place pieces'of felt F, which ill up the space between the partitions. 'lhel felt is continually saturated with oil, which is contained in the reservoirs or chambers G G, there being openings d inthe partitions c c, through which the oil passes to the' felt, and which is constantly supplied to the journal B by capillary attraction.

The upper .edges of the felt project 'a little above the concave face a ofthe box D, to prevent the latter touching the journal B, and to allow the felt to he kept up, so as to gently touch the journal, by the action of the spring E, for the lubrication ofthe saine.

The concave surface a of' the top of the box serves to catch the oil which would otherwise escape from the journal as its periphery passes overthe felt. TheA escaping oil thus preserved as it incliues to thefe-lt is again taken up and redistributed to the journal. l There are suitable openings in the top of the oilbox D'for the purpose of supplying the chambers G G with oil. These openings are closed by `means of screw-plugs e e, or otherwise, so as lto prevent anyvdirt passing into t-he oil. l

It will readily appear that the lubrication of the journal as it revolves must be kept up in a complete andv perfect manner, in consequencek of its contact with a large body of felt, which is constantly saturated with foil from'the' reservoir, as long as any remains in them.

If, under some circumstances, it may be seen that the oil is fed to the journal too freely, the diicnlty may be obviatedby diminishingv the thickness of the felt-F, thereby causing a slower motion to the passage of oil.

I do not coniine myself to the use of felt between the partitions c c, as I contemplate using leatherror other tbrous or porous material in its place.

Vhat I claim as my invention, and desire to secure Iby Letters Patent, is-

Th oil-box D, having `side oil-chambers G Gr and perforated vertical partitions c c, between which felt or other brous or porous material F is held, the said box having a concave surface, a, and being held up by means of a spring, E, all in the manner and for the purpose set forth. 1

In testimony that the above is my invention, I

have hereunto set my hand and affixed my seal. this y7th day of April, 1870.
